The Hayward Fault is regarded as one of the most hazardous faults in California, and perhaps the world, because it traverses the highly urbanized zone between the San Francisco Bay and the East Bay Hills. Hospitals, police and fire departments, universities, and a major international airport are also located in this potentially hazardous seismic corridor. Thus, studies related to understanding and mitigating earthquake hazards associated with the Hayward Fault are important to the safety and economy of northern California, and are applicable to earthquake hazards worldwide. As a result of this Workshop, we recognize a number of unanswered questions and unresolved issues, and recommend a number of scientific studies that might address them. Some of the more important issues include the extent of the 1868 earthquake, whether or not the fault is segmented, the rate and depth extent of creep, and the nature of the connections between the Hayward Fault and the Rodgers Creek Fault to the north and the Calaveras Fault to the south.
